In Cuba December 30, 1941 2 Claims.

This invention relates to doors, windows and like objects as, for example, window blinds, shutters, etc., and it has for its object to provide doors, windows, and window blinds with sash units made of two panels of transparent material which are joined togetherat their edges but are separated at their inner areas to provide an interspace adapted to be filled with'a colored fluid apt to render the door or window sections and the window sash units opaque, thereby preventing the direct action of the suns rays upon the persons within a room. The colored fluid may be inserted or withdrawn at will by means of controlling valves associated with a pump or means for feeding the colored fluid and withdrawing the inner air or for withdrawing the colored iiuid and supplying outer air, depending upon whether the user desires to maintain the sectionsl of the door, window or window-blind opaque or transparent.

The invention is described with reference to the gures of the accompanying drawing, of which: i

Fig. 1 is a front elevation of a window closure embodying the invention.

Fig. 2 is a detailed front elevation of a sash unit or section of the closure on a larger scale and partly in section.

Fig. 3 is a vertical transverse sectional view of the sash unit.

Fig. 4 is a vertical sectional view through supporting elements of the sash unit showing the means for supplying and withdrawing the fluid inelevation, this view being on a larger scale than Fig. 2.

Fig. 5 is a horizontal sectional view through the support of a sash unit partly in section and through portions of the frame.

Fig. 6 is a side elevation of a bearing bushing.

Fig. 7 is an end elevation of said bearing bushing.

Fig. 8 is a sectional view through a sash unit adjacent its supporting element, this view being taken on a scale similar to that of Fig. 4, and this view being taken on the line 8-8of Fig. 2, and

Fig. 9 is a 'transverse sectional view through a bearing element for the sash unit and portions of the supply elements for the fluid.

In Figs. 1 to 9 both inclusive ls illustrated the the application of the invention to the sash units 46 of afranie 41. Each sash is composed of two panels 2 and 3 of transparent plastic materialV the upper and lower edges of which form inclined engaging surfaces with a projecting tooth I0 at the top and a projecting tooth l' at the bottom so that as all sash units 46 of the frame d1 are placed in vertical position, the upper edge of one sash unit will closely engage the lower edge of the adjacent sash unit, thereby preventing air and rain fromentering the room.

Each sash unit 49 has at one end a journal vplates 53 and 5l which diametrally project from each bushing at its inner end and are inserted within the solid material formed at each end of each sash unit d6, each wing 5i) and 5l having a pair. of holes 52 and 53 respectively through which pass the screws .securing said wings 59 and 5| to the sash unit d6. The bushing i9 closed at its outer end is rotatably mounted in a metallic bearing 54 fixed by screws 55 on the side surface of a recess formed in the respective side'of the frame lll. The bushing 48 is rotatably mounted in a metallic bearing 56 secured by screws 5l to the inner side of a metallic channel 58 inserted in a longitudinal recess 59 formed at the edge of the opposing side of the frame fil and laterally closed bya wooden cleat 60, the channeled casing 53 having its edges bent to form longitudinal flanges 5l and 62 which are applied against the inner faces of the cleat and the frame 41 itself and are secured thereto by screws 63 and 6G, as shown in Fig. 5. Each bearing 56 has two diametrally opposed holes, one upper hole 55 and one lower hole 6E, to which are connected the vertical ends of two elbowed-tube branches 6l and 58 joined to the vertical tubes 59 and lll lodged within said casing 58l and which are respectively in communication with the air tank 28 and with the colored fluid tank 26 actuated by the pump 21 all three mounted on the lower portion of the frame' lill. The two halves 3U of each solid journal have formed at their joint surfaces two angular conduits 39 extending axially therethrough and ending at one end in front of lholes Il and 'l2 formed in bushing 48 in diametral alignment,

said conduits 30 being extended transversely through the joint surfaces of the panels 2 and 3 until ending at the other end in the upper space 5 of the sash unit 46. The holes 1| and l2 are in alignment with the two wings 50 and 5l, so that when the sash units are in a position other than in a vertical position, the holes ll and 'l2 will not register the holes B5 and 66 of the bearing 56, but as the sash units 46 are placed in vertical position details of construction and assemblage of the.

slidable sections of a door or window sash and oi! the sash'units, Without thereby altering the essential character' of the invention which is such as claimed hereinafter.

What I claim is:

1. A door or window closure, comprising in combination with a frame, a sash unit assembled of two transparent panels with an interspace between the same.` the panels having sealing portions along the marginal formation thereof adapted to conne the intel-space against the outer atmosphere, pivots projecting from the sash unit in opposite directions, bearings for said pivots secured to the frame. means for supplying and withdrawing a fluid through one of said pivots to and from said interspace, said last named means being operable solely when said sash unit is moved to a position in which the opening of the frame is closed thereby.

. units each consisting of two transparent panels with an interspace between the same, the panels havingy sealing portions along the marginal formations thereof adapted to confine the interspace of each panel against thekouter atmosphere, pi ots projecting 1from each sash unit in opposi e directions and in axial alinement with each othe bearings mounted on the frame for supporting said pivots, one of the pivots on leach sash unit -beng provided'with passages extending therethrough and connecting the interspace between said panels with diametrically opposite openings in the periphery'of said pivot, the bearings for said last described pivots having diametrically opposite openings adapted to register with the peripheral openings inthe pivots upon the sash units being 'placed in a position parallel to the plane of the frame, conduits extending from the openings in the bearings, and means for supplying and withdrawing avfluid through one of said conduits to and from said interspaces of said sash units, said last named meansbeing operable solely when said sash units are moved to a position in which theopening of the frame is closed by the same.-
